초록

The reduction of $Ni(OH)_2$ by hydrazine-sodium phosphinate in water and water-diethylene glycol solutions for the preparation of spherical nickel particles has been studied at room temperature. The effect of reaction conditions on the size and morphology of Ni powder was revealed using SEM and XRD analysis technique. It was shown that in the presence of sodium phosphinate the reduction process become activated and a formation of Ni particles was completed within several minutes at room temperature. As a desired result spherical Ni powders with particles size from 0.07 to 2.0 mm were obtained.
